These cartridges carry the name "Beagle Brothers" on the label, although they were not produced by the similarly named Beagle Bros software developer who published home computer software in the 1980's. We have spoken to several ex-Beagle Bros employees who are unaware of any Atari 2600 carts produced by the company. We believe they are pirate carts originating in South America due to the nature of the circuit boards contained within. The "Beagle Brothers" name was likely used to capitalize on the popularlity of the brand at the time.

The games themselves are simply repackaged versions of existing titles from Activision, Atari, Parker Brothers, and other companies. Due to the simple nature of the labels, it is likely that reproductions of these cartridges are floating around. Beware of fakes in the collector market.
